DETAILED DESCRIPTION

Embodiments of the present disclosure will be described in detail. Examples of the embodiments are shown in the drawings. The embodiments described herein with reference to drawings are explanatory, and used to generally understand the present disclosure, and shall not be construed to limit the present disclosure.

In the following, a washing-drying machine 100 according to embodiments of the present disclosure will be described with reference to FIG. 1 to FIG. 4.

As shown in FIG. 1 and FIG. 2, the washing-drying machine 100 according to embodiments of the present disclosure includes: a cabinet 10, an inner drum 20, a condenser 30 and a filter 40. Specifically, the inner drum 20 is rotatably disposed in the cabinet 10, the inner drum 20 defines an accommodating cavity therein and has an air outlet 21 communicated with the accommodating cavity. The condenser 30 is disposed in the cabinet 10 and defines a condensation channel (not shown) together with the cabinet 10, and the condensation channel is communicated with the air outlet 21. The filter 40 is detachably disposed in the cabinet 10 and located between the air outlet 21 and the condensation channel, and the filter 40 has an inlet 401 communicated with the air outlet 21 and an outlet 402 communicated with the condensation channel, and is further provided with multiple layers of detachable filtering pieces 41.

In other words, the washing-drying machine 100 mainly includes the cabinet 10, an outer tub (not shown), the inner drum 20, the condenser 30 and the filter 40. The cabinet 10 extends along a vertical direction (i.e. an up and down direction as shown in FIG. 1), the outer tub is fixed within the cabinet 10, and the inner drum 20 is rotatably disposed in the outer tub. An external circumferential wall of the inner drum 20 and an internal circumferential wall of the outer tub are spaced apart from each other. The inner drum 20 defines the accommodating cavity therein to accommodate clothes, the inner drum 20 has an air inlet (not shown) and the air outlet 21 communicated with the accommodating cavity respectively. Optionally, axes of the outer tub and the inner drum 20 extend along a front and rear direction respectively, i.e. an opening of the inner drum 20 faces forwards.

Further, the filter 40 and the condenser 30 are both disposed in the cabinet 10. The condensation channel is defined between the condenser 30 and the cabinet 10, and the filter 40 is detachably disposed between the air outlet 21 of the inner drum 20 and the condensation channel to filter air before the air enters the condensation channel, so as to prevent the soft flocks of the clothes from entering the condensation channel and influencing the operating efficiency of the condenser 30. When the washing-drying machine 100 enters a drying program, wet air in the inner drum 20 enters the filter 40, and the filter 40 filters out the soft flocks in the air. Cleaned air is condensed and heated through heat exchangers (such as an evaporator and the condenser 30), and then enters the inner drum 20 to dry clothes, and so on.

As shown in FIG. 1, a side wall of the cabinet 10 is disposed with an access port A, and the filter 40 is disposed adjacent to the side wall of the cabinet 10, so that a user can take out the filter 40 through the access port A to clean the filter 40 and then mount the filter 40 back into the cabinet 10 through the access port A after cleaning the filter 40, without disassembling a machine body of the washing-drying machine, thus resulting in convenient assembling and disassembling, as well as easy operations, regardless of a placing position of the washing-drying machine 100. The filter 40 has the inlet 401 and the outlet 402, in which the inlet 401 of the filter 40 is communicated with the air outlet 21 of the inner drum 20, for example the filter 40 may be in communication with the air outlet 21 of the inner drum 20 through a pipe 22, and the outlet 402 of the filter 40 is communicated with the condensation channel. The filter 40 is further provided with the detachable filtering pieces 41 therein, which are convenient to assemble, disassemble, replace and repair.

In the washing-drying machine 100 according to embodiments of the present disclosure, by disposing the detachable filter 40 in the cabinet 10 and the detachable filtering pieces 41 in the filter 40, the air can be filtered before entering the condensation channel so as to prevent the soft flocks from entering the condensation channel and influencing the operating efficiency of the condenser 30, and also, a user can also detach the filter 40 and clean the filter 40 rapidly and conveniently, thus improving the usage convenience for the user. The filter 40 of the washing-drying machine 100 has a simple and compact structure and is convenient to assemble and disassemble with a high efficiency.

Optionally, according to an embodiment of the present disclosure, the filtering pieces 41 may be detachably disposed between the inlet 401 and the outlet 402 or at one of the inlet 401 and the outlet 402. Thus, the air can be filtered before entering the condensation channel and the soft flocks of the clothes are prevented from entering the condensation channel and influencing the operating efficiency of the condenser 30.

In some specific embodiments of the present disclosure, the filtering pieces 41 are disposed at the outlet 402. Specifically, as shown in FIG. 2 and FIG. 3, a casing of the filter 40 is provided with the inlet 401 communicated with the air outlet 21 and the outlet 402 communicated with the condensation channel, i.e. the inlet 401 of the filter 40 is communicated with the air outlet 21 of the inner drum 20 and the outlet 402 of the filter 40 is communicated with the condensation channel, and the filtering pieces 41 are disposed at the outlet 402 of the filter 40 so as to filter the air at the outlet 402. Thus, by disposing the filtering pieces 41 at the outlet 402, it is convenient to assemble and disassemble the filtering pieces 41, and due to a large size of the outlet 402, a filtering air amount in unit time can be increased and thus the operating efficiency of the filter 40 can be improved.

According to an embodiment of the present disclosure, a plurality of air guiding plates 42 is disposed between the inlet 401 and the outlet 402, and an air channel 403 is defined between two adjacent air guiding plates 42 and is communicated with the inlet 401 and the outlet 402 respectively. Specifically, as shown in FIG. 3, the plurality of air guiding plates 42 is arranged in the filter 40 and spaced apart from one another, the air channel 403 is defined between the two adjacent air guiding plates 42, and two ends of the air guiding plate 42 extend towards the inlet 401 and the outlet 402 respectively, i.e. one end of the air channel 403 is communicated with the inlet 401 and the other end of the air channel 403 is communicated with the outlet 402. Thus, by disposing the air guiding plates 42 in the filter 40, the air can be guided to disperse uniformly, so as to make the air condensed and heated by the heat exchanger (such as the condenser 30 and the evaporator) more sufficiently.

Preferably, according to an embodiment of the present disclosure, each air guiding plate 42 is configured as an arc-shaped plate extending from the inlet 401 to the outlet 402 in an arc transition manner. Specifically, as shown in FIG. 4, the plurality of air guiding plates 42 extending from the inlet 401 to the outlet 402 in the arc transition manner are provided between the inlet 401 and the outlet 402 of the filter 40, and the plurality of air guiding plates 42 is spaced apart from one another to define a plurality of the air channels 403, so that the air can be guided to disperse uniformly, and thus the air can be condensed and heated by the heat exchanger (such as the condenser 30 and the evaporator) more sufficiently, and also, an air flowing direction can be changed on the basis of decreasing an energy loss of the air.

According to an embodiment of the present disclosure, the filter 40 includes a filter box 43 and a filter cover 44. Specifically, the filter box 43 defines an air guiding cavity therein, the filter box 43 has the inlet 401 and the outlet 402 communicated with the air guiding cavity respectively, and the filter cover 44 is detachably connected with the filter box 43.

In other words, the filter 40 mainly includes the filter box 43, the filter cover 44, and the filtering pieces 41. The filter box 43 defines the air guiding cavity having an open top end, and side walls of the filter box 43 have the inlet 401 and the outlet 402 communicated with the air guiding cavity respectively. The filter cover 44 is detachably disposed to the filter box 43 to enclose the open top end of the air guiding cavity. The filtering pieces 41 are detachably disposed in the filter box 43 and located at one of the inlet 401 and the outlet 402 or between the inlet 401 and the outlet 402, and the air guiding cavity is configured to have an arc shape extending from the inlet 401 to the outlet 402 in the arc transition manner.

Thus, the filter 40 has a simple and compact structure, is convenient to assemble, disassemble and repair, and can filter the soft flocks in the air and also have a function of air guiding.

Optionally, according to an embodiment of the present disclosure, the filter box 43 is configured to have a rectangle shape, and the inlet 401 and the outlet 402 are provided in two adjacent side walls of the filter box 43 respectively. Specifically, as shown in FIG. 3 and FIG. 4, the filter box 43 is configured to be a rectangular box extending along a horizontal direction (i.e. a front and rear direction as shown in FIG. 3), the inlet 401 is provided in a short side wall of the filter box 43 (i.e. a rear side wall as shown in FIG. 3), and the outlet 402 is provided in a long side wall (i.e. a right side wall as shown in FIG. 3) adjacent to the short side wall. The filtering pieces 41 are detachably disposed at the outlet 402 to filter the air before the air enters the condensation channel.

Due to the large size of the outlet 402, the filtering air amount in unit time is increased, and the operating efficiency of the filter 40 is improved. Furthermore, the air disperses uniformly, thus making the air condensed and heated by the heat exchanger (such as the condenser 30 and the evaporator) more sufficiently.

The filter box 43 and the filter cover 44 may be detachably connected with each other by a bolt or a snap structure. Certainly, the present disclosure is not limited to this. For example, as shown in FIG. 3, the filter cover 44 is pivotably connected with the filter box 43. When the soft flocks on the filtering pieces 41 need to be removed, it is only needed to take out the filter 40 through the access port A, then open the filter cover 44 and further take off the filtering pieces 41 to clean the same. After the soft flocks are removed, it is only needed to mount the filtering pieces 41 back, close the filter cover 44, and finally mount the filter 40 back through the access port A. In these above processes, the filter cover 44 does not need to be taken down completely, which improves the usage convenience for the user and provides a high assembling and disassembling efficiency.

In some specific embodiments of the present disclosure, the filtering pieces 41 may include a filtering mesh, and a single layer of the filtering mesh may be provided. Certainly, the present disclosure is not limited to this. For example, the filtering pieces 41 may also include a plurality of filtering meshes, and the plurality of filtering meshes is disposed while overlapping one other. Optionally, the plurality of filtering meshes is disposed at the outlet 402 while overlapping one another. A shape of each filtering mesh may be same with a shape of the outlet 402 of the filter 40. For example, the outlet 402 of the filter 40 and the filtering mesh each have a rectangle shape. The plurality of filtering meshes is arranged in respective layers and disposed at the outlet 402, which can perform a multi-layer filtering, improve the filtering function and effect of the filter 40, and further effectively prevent the soft flocks of clothes from entering into the condenser 30 or other components and blocking channels. In addition, the plurality of filtering meshes is detachable from the side wall of the filter box 43, which facilitates assembling and disassembling of the filtering meshes and is convenient for repair and replacement.
